Damage equivalence factors for the fatigue verification of orthotropic steel decks of highway bridges

摘要

For the fatigue verification or determination of the remaining fatigue life of steel highway bridges, based on the Eurocode, in general the simple fatigue load model ELM3, consisting of one vehicle only, is used and the effects of the complex traffic behaviour are considered by damage equivalence factors lambda. However, the application is limited to span length and length of the influence lines L > 10 m.
